What 6-inch shells do at extreme close range

At roughly 60 meters, could cruiser 6-inch guns depress far enough to threaten an opposing ship's magazines rather than only its superstructure?

Even with about five degrees of depression, the shells could wreck structural integrity, ricochet inside the armor belt, and possibly ignite magazines. A target left afloat could still be beyond repair.

The question tests whether turret depression would keep cruiser shells from reaching a target's vital spaces at an extraordinarily short range. The guns could depress only about five degrees, yet repeated 6-inch hits would still tear through the ship and destroy its structural integrity. Shells entering the upper structure could ricochet from the inside of the armor belt and detonate within the hull, with unpredictable paths and the possibility of reaching magazines. Survival afloat would not mean the ship remained repairable or combat-effective.
